Giving a mob/player potion effect

I have been trying to figure this out for a couple hours, but it doesnt work.
Can someone show or make me a code that if you hit a player/mob it is being set on posion for some seconds?

 

player.addPotionEffect()

 

Handle an EntityDamageByEntityEvent, if the damager is an instanceof player (and maybe if he has a permission), give the entity a potion effect?

 

So after reading your other post on this and seeing that you cant apply a potion effect to the Entity class you can try

Code:

LivingEntity entity = (LivingEntity) event.getEntity();
        entity.addPotionEffect(new PotionEffect(PotionEffectType.CONFUSION, 20, 1));

This casts the entity to a living entity where we add a confusion effect to the entity for 20 ticks which is equal to 1 second.

 

ProFatal Sorry to bump such a old, dusty thread but I don't think making a new one would be as good.
How can you give an effect forever?
